If it takes several thousand cycles to make this "defect" show up, I think I understand why Wildalaska doesn't see it in .30-30s, .45-70s, or .444s. AT least I feel comfortable that my 1895 in .45-70 will never show a sign of it, as least not til it's in the hands of grandkids yet unborn. I may have put 500 rounds through it in 15 years.
